Power Pads really do provide more power

OK, I have a question, how do you make power pads, and where do you put them? I have a bunch of leather, so what do I do?

Thanks,
Volt
Volt, power pads are simple peices of leather. Just cut out a small square or rectangle (small enought to fit under you strings), and place them in the throat. I make them from the leather strings used to string up baseball gloves. They are flat pieces of string, so they fit nicely under the string.

 
power pads do decrease the angle of the string in the frame like everyone else is stating already. they also provide more power to a racquet. Power pads increase the length of the main strings where the power pads are placed... this acts like the babolat woofer technology and provides the racquet with more power.

i don't know.... I tried power pads out for the first time today and they were pretty powerful.

I strung up Gosen Micro 17 at 60 pounds on a slaz x1 with powerpads at the throat. Earlier in the day I was having trouble generating much power on my E-matrix 16g 60lbs setup -- which is weird... as it generally did play pretty powerfully... May game picked up and I played as usual, but when I switched to the gosen/pads it was extremely powerful.

Then again, I've only recently started messing around with full syn gut setups again. I've basically been a poly guy all school year.

I'm gonna string another racket up without pads and the same setup and give my personal opinion on what the differences are. Thankfully I broke strings on 2 of my three rackets today....

I should say, that although i hated the gosen/pads at first -- couldnt keep the ball in play!!! when I switched back to it (because I had no other rackets left) I really liked it. Thinking about it now, it may just be that i needed to break in the gosen. I remember now the first time I played with it i hated it for the first half hour or so, and then it started to shine...

I'm sorry, but how can power pads increase the power of a frame when they are compressed by around 60 pounds of tension? They do not compress and release energy back to the frame. The little strip of leather is already compressed down as far as it can go with the tension applied to the strings.

The only reason they exist is to eliminate sharp angles which can shorten the life of string jobs, most notaly natural gut.

Most of today's rackets have grommet systems built to accommodate this. I only use them when stringing a couple of Yonex frames with natural gut as they have sharp angles.
There is still some give in the leather pads, even under tension. Would you think a stiff piece of plastic feels softer than compressed leather? I think not!

And, are you aware that there are newer power pads made of plastic? I have a bag of these. They are little plastic pieces that are designed to deflect the angle of the string. They were also designed, as a convenince, to replace the leather power pads.

So, yes, I agree that plastic doesn't give, and you are wrong. If you'll examine those leather power pads, you'll see that they are compressed. If there is any "give", it's negligible and doesn't contribute anything to the power of the frame.

Again, it's solely to increase the life of natural gut or any other string.

Drakulie - how does one actually fit these pieces of leather/power-pads under the string: during the stringing itself or can you slip them through between string and grommet afterwards? :confused:

^^^ You have to place them under the string before tensioning it. You place them under the loop, and then tension the string.

That's just your opinion--without factual basis. I don't see why you have to force your opinion on someone--unless you're a CHILD who needs validation from everyone.

do power pads dampen just a tad? I wouldn't mind a slight dampening effect without using a vibe damp. I been vibe damp free for a year now and i like it. I just need a tiny bit dampening and it would be perfect.

^they really don't. All they do is change the angle of the string. Leather was used because what else do you do with old grips? They made these little plastic ones for a while, I don't think they do any more, and they were ok if your frame was flat on the outside. If the grommet sunk in any, they would break under the string tension and were basically useless.

They take away some of the vibration in the mains. Sometimes when I use them, I don't even use the vibration dampener.

I don't see why you can't just try it out for yourself.

exactly. have no idea how they became known as "power pads".

some racquets even have rounded grommets so you don't need to use power pads.

my stringer (who strings at grand slams) still uses them when he strings with gut but says it's just habit and he doesn't really need to use them.

You do it after the stringing is done. You just lift up the string on the bridge of the racket and slip them in..;)

Please explain. Because the leather slowly submits to the tight string, thereby compressing and slowly losing tension.

I see no other way to look at it.
I know the very tight tension in the string will provide extreme heat on the power pads and the power produced by the power pads produced chemical reaction and million of degree of heat that made the world trade center to come crashing down.;)

Yep, most manufacturers have realized that the angle was something they could correct with grommets and have done so. I very seldom get to use them, the only frames now are pretty much Yonex frames that come in. The rest are taking care of it with the grommets.

I don't think that the power increase is that pronounced.

power pads do longer the strings by a very slight margin, which could produce a little more liveliness

they do also have the effect of adding a little weight to the hoop of the frame, which could inrease power very very slightly.

but I don't think that with today's modern frames, as powerful as they are, most people will ever get to notice that power. Maybe if you're using a PC600 or PS 6.1, you will notice the power gains from power pads a little more,
which might be why we mostly see players like sampra, federer and safin use them in the past......

just a thought...

This is an example of "overthinking" gear. The added string length is probably not even measurable. I dare say 6 leather power pads don't weight a gram and they are not placed so as to add weight in a strategic location to add power.

The reason sampras used power pads was the same reason everyone else used them, to keep his gut from breaking.

What are you talking about? I'm confused.
If you look at the grommets produced today, many of them have built in "power pads" of sorts. The grommets are rounded where they need to be to deflect the angle of the string thereby eliminating the need for power pads.

Like I said..I don't think the very slight added power of power pads are even noticeable on most of today's powerful rackets....

but the physics point to the conclusion that power pads should theoritically provide a very minor increase in liveliness in your stringbed.

you can't argue physics... longer string = more power
more mass = more power

0.3% increase in weight + 0.5% increase in length = statistically insignificant.
Unless you can sense a dramatic difference in a 2lb looser sting bed (0.8%) I am not going to believe power pads make enough of a difference. You can't argue the math.

In Federer's case I would believe that between the change in vibration frequencies and 0.8% difference in power he might care. Very few of us are in that league.

Have any of you who speak of power pads tried them out in real life? If not, then it's time to pipe down and actually try them before making any further statements.

Where do you think the numbers come from?
Furthermore, as I reflect on it the angle theory holds more water with Federer due to his reverse Hybrid pattern. If he used the conventional poly main gut cross even he would abscond from power pads.

I tend to believe your "feel" argument for Federer's case. I doubt he has them for string life. Doesn't he switch frames every ball change? Are his racquets ever re-used from one match to another? Some goes for his use of string savers. It must be for feel.

Well yeah. I grew up playing with wood when EVERY string job had them. I further used them when I strung my Yonnies back when I played with an R7. I didn't use them on my RD-Tour because it quite frankly didn't need them and I wasn't using gut at the time.

I used them as recently as a couple of years ago when I got a wild hair and played an entire year of league (spring, mixed, and combo) with a bunch of Head Vilas frames. Now, they did need them because I was stringing them with Pacific Natural Gut.

So yeah, I have experience with and without them.

Can you answer same?

Doesn't Federer use gut mains and poly crosses?

Also, looking at pictures of Federer's frame during Hamburg and the Russel match, it does not appear that he even uses power pads....

Check your eyesight again. And to make a long answer short, YES I have/am.

I have been using them for about 2 years now.

I can definitely tell a slight difference in my string be being a little more lively/more feel with power pads.

however on some of my older frames I could not detect any increase power...but with my PC600 I can detect the very slight difference.

after i strung my racket with power pads, i seemed to lose tension really fast. is that because the leather is being compressed??

have you tried those strings before? maybe you're changing too many factors at once and getting ahead of yourself.

"statistically insignificant"? How do you know this? Did you run a regression on the results or something? "Statistically insignificant" implies a specified significance level (0.1, 0.05, 0.01; which are the typical levels used in research). What significance level were you using when you did your analysis? What is your threashold for insignificance? What was your regression coefficient(s)? I think you see my point. I agree with you that it seems like such measurements WOULD be insignificant (i.e. not make a difference to the tennis player), but you can't just say something's "statistically insignificant" unless you actually used a statistical model. If you did, then please let us know so that we can interpret your findings. I know that us equipment geeks would be interested :)

I don't think Gimmick has ever tried power pads before, nor has he ever touched a tennis racket strung with them, so lets just ignore him from now on. It would def. save us a lot of time from reading/responding to his BS.

Great point.... what feels insignificant to one person, could feel totally different to another..... Again I repeat..I think the kind of frame you use, and how much flex/feedback you have from your racket will determine if you can sense any difference with power pads or not.

I would welcome any posts where someone else uses a caliper to measure a previously compressed "power pad", weighs it on a calibrated scale, and develops their own difference in power levels based on change in a racquet they are familiar with. Until there is compelling data opposing my findings, I stand by them.

Just tried power pads for first time in my raquet. I asked my stringer why they call them power pads, instead of just leather pads, and he said that since the pads actually provide a little more give on the main strings that they are used on (which basically consists of the main strings in the sweetspot of the racquet), this increases the string bowing effect, which increases dwell time and ultimately does provide the sense of having more power in the racquet.

He said that is why they fold them several times, because they provide slightly more "give" than just one layer. he said also because it slightly lengthens the strings in the sweetspot, and that makes sense too, as oversized racquets have much more power than mid and Midsize frames.

Any thoughts on this.... Seemed to make sense to me. and I can definitely feel the difference in my PC600.

by the way he said that they should be replaced at each striniging because as leather gets worn down, it looses it's "give" to the main strings which reduces the extra "bowing", or "cupping" effect, which is why natural gut is known as the ultimate power string, because of the extreme bowing or cupping effect of the ball.
Did your stringer say how much the power pads weigh?
